Microsoft AutoUpdate TD

Office for Mac that comes with a Microsoft 365 subscription is updated on a regular basis to provide new features, security updates, and non-security updates.
Updates are available from Microsoft AutoUpdate (MAU).

To use Microsoft AutoUpdate, start an Office application, such as Word, and then choose Help > Check for Updates. If you're an admin and want to update the computers in your organization with your existing software deployment tools, you can download and deploy the update packages for each application.
